Thanks. I really wasn't worried about performance. The main system is
running on a single drive and I was planning on the raid array just for
simple storage with a little redundancy.
I do have another one of these exact drives, but I'm not sure how to
progress since I screwed up the original creation of the array. I
wouldn't mind just salvaging what I can and starting the array over.
What do I do about the fact that I originally had dev/hdd and
not /dev/hdd? Or once I salvage the data should I start over?
By the way, these are 160 gb disks, any idea how long it will take
dd_rhelp to finish? It's definitely run into some issues on the suspect
drive, but it's still plugging along.
